1) 3^2 × 3^3 = (3×3)×(3×3×3) = 9×27 = 243
2) 3^1 × (3^4) = 3×(3×3×3×3) = 3×81 = 243
3) 3^0 × (3^5) = 1×(3×3×3×3×3) = 243

I'm not 100% sure if these are all correct, so please forgive me if I'm wrong.
Hopefully this helps, and please consider marking branliest.
Tan because sin is opp/hyp cos is adj/hyp and tan is opp/adj
34 is the opposite because it is across from the angle that needs to be found and 48 is the adjacent
x = 6
given x varies inversely with y then
xy = k ← k is the constant of variation
to find k use the condition x = 4 when y = 9, hence
k = 4 × 9 = 36
x = 
← inverse variation equation
when y = 6, then x = 
= 6
1250 × 6.5% is 81.25 add that to 1250 and get 1331.25.
